ABSTRACT:
An instant camera is provided with a motor rotatable in normal and reverse directions, a claw member for pushing an exposed film unit out of a film pack, and a pair of spreading rollers for ejecting the exposed film unit from the camera by applying pressure thereto. The motor rotates in the normal direction upon taking a photograph, so that the spreading rollers rotate in normal directions. The force of the motor is simultaneously transmitted to the claw member via a clutch mechanism. An operable member is provided in a film pack chamber. To clean the spreading rollers, the door of the empty film pack chamber is opened. When the operable member is pressed, the motor starts rotating reversely. During the resulting reverse rotation of the spreading rollers, a cloth for wiping the spreading rollers can be applied thereto, so that processing solution or dirt sticking to the rollers can be removed. Reverse rotation of the motor is prevented by the clutch mechanism from being transmitted to the claw member.
